DUMPING-HQPPER VEHICLE.

To all whom it may concern:

Be it known that I, ALBERT'P. LEE, a

citizen of the United States, residing at position when loaded.

My invention relates more particularly to hoppers of the kind which areadapted substantially automatically to roll from a charge carrying to adischarge position, the preferred form of course contemplating thisrolling action to both sides'of the central position.

In accordance with my invention I utilize a hopper of these. generalcharacteristics, and in the specific illustration used herein I havetaken the hopper shown in co-pending application Serial No. 142,419,filed Jan. 15, 1917. In hoppers of this character it has been found thatthe curvature of the hopper body, or in fact the whole general outlineof the hopper body must be maintained in order to have propercooperation between the hopper and the rail on which it rolls. 1 To thisend my invention concerns itself with the specific hopper constructionwhich I will now describe in detail in connection with the accompanyingdrawings illustrating the same,

in which Figure 1 1s an-end view of a vehlcle' constructed in accordancewith my invention;

Fig. 2 is a fragmentary sectional view on line 2-2 of Fig. 1;

per 18 and on which said hopper rolls. 'The hopper itself, as moreclearly apparent from Figs. 1, 2, 3, 5 and Thas the channels 14, wh chare adapted to cooperate with the rail 12. These channels are providedwith holes 15 adapted to cooperate with lugs 16 projecting from the rail12 so as to keep the hopper in its proper position vrelative to therails. Across the bottom portion of the channels a tension element"l'i'yshown more clearly in Fig. 7 is providcd ,*-which= tension elementthrough the agency: of 'its arms 18 1s securely riveted at its -meeting"point with the channel 14 by the rivets '19.

This tension element 17 thus prevents flattening of the lower curvedportion 20 of the channel 14; By reason of the addition of this tensionelement the hopper is thus maintained in its original configuration oroutline.- Tlie hopper structure is then completed through the additionof the'sheet .metal portion 21 which forms the floor and sides of thehopper, and which is of course of substantial thickness. The hopper isthus made up of this box structure .21 together with the channels 14 andthe tension elements 17, there being of course as many channel elements14 as there are rails 12, there being usually at least two rails [perhopper. The rails 12 are supported at their extremities by the arms 22'and these rails likewise carry the locking brackets 23.

In Fig. 6, I show a modified formof the structure shown in Figs. 1,2,3,5 and 7 in that the sheet metal body portion 21 of the hoppemextendsalong the entire length of the channel 14. A. tension element 17 isprovided which is riveted to the hopper as shown by the bolts 24 andthus serves its purpose of preventing flattening of'the hopper bottom.These tension elements 17 i may of course be used-for the additionalpurpose of a support for a false bottom indicated by the boards 25. Theboards 25 of course may be omitted at times so. that the entire hoppermaybe filled with vmaterial, Which' it is desired to convey.

In order to lock the hopper in its central position I provide a bolt 26carried upon a stem 27, which stem is mounted in the lugs 28 and "29carried at theentremity of the hopper. A spring 30 tends to press thestem 27 together with its bolt 26 downwardly through the agency ofi thecollar .31 proa the other of the-links moves its c'otiperat:

co said railwhereby said hopper is adapted to vided upon the'stem 27 Thestem is :preferably square-where it passes through the lug 29 so as toprevent rotation thereof. This ,bolt cooperates with the recess or notch32 provided in the block .33 carried by the framework 34. \Vhen thebolt' is in its position by the block 36. This pin 35' has fingers37, 38adapted to cooperate respectively with slotted links 39 and 40. Theseslotted links are carried at extremities of arms 41, 42, carried by theshaft 43. This .shaft is rotated through the agency of the handle 44. v

Now whenever the handle 44 is rotated to either side of its centralposition one or ing pin 37V or 38 upwardly, thereby moving the pin'35upwardly until its top surface projects above the top of the plate 45,

immediately subsequently to which the bolt 26 passes out of the recess32, whereupon the hopper may roll to its discharge position. It willbeunderstood of course" that as soon as the top surface of the pin 35proects above the top surface of the plate 45 that thenthe stem27 isthenno longer confined by the plate 45, the bolt 26 having been released,the hopper may roll to the side desiredi when the hopper is rolled backto .its central posltion the bolt 26 ride-s over one or the other-ofthecam surfacefl 46 or 47 until it alines, With the recess 82 and snapsinto position due to the agency of the spring 30 to thereby hold thehopper in its central position. It will be apparent that a rotation toeither side of the central position of the handle 44 will occasion'arelease of the hopper fromits locked position. When the stem 27 movesdownwardly .upon the alinement of the bolt 26 and recess 32 it pushesthe pin- 35 downwardly, which thereupon rotates the shaft 43 into itscentral position with the handle 44 standing vertical.

From what. has been thus described the" nature of my invention will bereadily apparent to thoseskilled in the art.

Having however .thusdescribed my invention, what I claim as new anddesire to secure by Letters Patent is:

Ina device of the character described the combination with arail,of a hopper adapted to roll on said rail from a charge c arryingto adischarge position, said hopper having arounded bottom to cooperate withroll substantially automatically upon said rail, and a tension elemento1n1ng the exdiseases placed in said hopper, the space below the tensionelement forming part of the interior of the hopper.
